The Accuracy Comparison of Oscilloscope and Voltmeter Utilizated in Getting Dielectric Constant Values
Proceeding The 1st IBSC: Towards The Extended Use Of Basic Science For Enhancing Health, Environment, Energy And Biotechnology 211 ISBN: 978-602-60569-5-5 The Accuracy Comparison of Oscilloscope and Voltmeter Utilizated in Getting Dielectric Constant Values Bowo Eko Cahyono1, Misto1, Rofiatun1 1 Physics Departement of MIPA Faculty, Jember University, Jember – Indonesia, e-mail: [email protected] Abstract— Parallel plate capacitor is widely used as a sensor for many purposes. Researches which have used parallel plate capacitor were investigation of dielectric properties of soil in various temperature [1], characterization if cement’s dielectric [2], and measuring the dielectric constant of material in various thickness [3]. In the investigation the changing of dielectric constant, indirect method can be applied to get the dielectric constant number by measuring the voltage of input and output of the utilized circuit [4]. Oscilloscope is able to measure the voltage value although the common tool for that measurement is voltmeter. This research aims to investigate the accuracy of voltage measurement by using oscilloscope and voltmeter which leads to the accuracy of values of dielectric constant. The experiment is carried out by an electric circuit consisting of ceramic capacitor and sensor of parallel plate capacitor, function generator as a current source, oscilloscope, and voltmeters. Sensor of parallel plate capacitor is filled up with cooking oil in various concentrations, and the output voltage of the circuit is measured by using oscilloscope and also voltmeter as well. The resulted voltage values are then applied to the equation to get dielectric constant values. Finally the plot is made for dielectric constant values along the changing of cooking oil concentration.

Equivalent Resistance
Equivalent Resistance Consider a circuit connected to a current source and a voltmeter as shown in Figure 1. The input to this circuit is the current of the current source and the output is the voltage measured by the voltmeter. Figure 1 Measuring the equivalent resistance of Circuit R. When “Circuit R” consists entirely of resistors, the output of this circuit is proportional to the input. Let’s denote the constant of proportionality as Req. Then VRIoeq= i (1) This is the same equation that we would get by applying Ohm’s law in Figure 2. Figure 2 Interpreting the equivalent circuit. Apparently Circuit R in Figure 1 acts like the single resistor Req in Figure 2. (This observation explains our choice of Req as the name of the constant of proportionality in Equation 1.) The constant Req is called “the equivalent resistance of circuit R as seen looking into the terminals a- b”. This is frequently shortened to “the equivalent resistance of Circuit R” or “the resistance seen looking into a-b”. In some contexts, Req is called the input resistance, the output resistance or the Thevenin resistance (more on this later). Figure 3a illustrates a notation that is sometimes used to indicate Req. This notion indicates that Circuit R is equivalent to a single resistor as shown in Figure 3b. Figure 3 (a) A notion indicating the equivalent resistance and (b) the interpretation of that notation. Figure 1 shows how to calculate or measure the equivalent resistance. We apply a current input, Ii, measure the resulting voltage Vo, and calculate Vo Req = (1) Ii The equivalent resistance can also be measured using and ohmmeter as shown in Figure 4.

Massachusetts Institute of Technology Department of Electrical Engineering and Computer Science 6.002 - Circuits and Electronics Fall 2004 Lab Equipment Handout (Handout F04-009) Prepared by Iahn Cajigas González (EECS '02) Updated by Ben Walker (EECS ’03) in September, 2003 This handout is intended to provide a brief technical overview of the lab instruments which we will be using in 6.002: the oscilloscope, multimeter, function generator, and the protoboard. It incorporates much of the material found in the individual instrument manuals, while including some background information as to how each of the instruments work. The goal of this handout is to serve as a reference of common lab procedures and terminology, while trying to build technical intuition about each instrument's functionality and familiarizing students with their use. Students with previous lab experience might find it helpful to simply skim over the handout and focus only on unfamiliar sections and terminology. THE OSCILLOSCOPE The oscilloscope is an electronic instrument based on the cathode ray tube (CRT) – not unlike the picture tube of a television set – which is capable of generating a graph of an input signal versus a second variable. In most applications the vertical (Y) axis represents voltage and the horizontal (X) axis represents time (although other configurations are possible). Essentially, the oscilloscope consists of four main parts: an electron gun, a time-base generator (that serves as a clock), two sets of deflection plates used to steer the electron beam, and a phosphorescent screen which lights up when struck by electrons. The electron gun, deflection plates, and the phosphorescent screen are all enclosed by a glass envelope which has been sealed and evacuated.

Uncertainty in Meter Readings
Uncertainty in Meter Readings Objective: To learn how to determine uncertainty of meter readings. Equipment: 1 D-cell battery per table Pasco analog voltmeter (one for two tables) DMM (one for two tables) 2 banana plug connecting wires per table Explanation: The accuracy of an analog ammeter or voltmeter is usually stated as a percent of the full-scale reading. The Pasco analog meters used in this course are accurate to ±2% of the full scale reading. Thus for a reading of 1.00V on a 3 volt scale, the uncertainty is ±0.06V. A reading of 1.0V on the 30 volt scale will have an uncertainty of 0.6V. For a digital multimeter (DMM), accuracy is usually specified as a percent of the reading, not the full scale reading. So a meter with a specification of 1% of the reading will read an actual value of 100.0V as something between 99.0V and 101.0V. Also, most manufactures specifications include a range of digits to the right of the percentage, e.g., ±(1%+2digits). This gives an indication of how many counts the last digit on the right can vary. So if a meter rated at ±(1%+2digits) measures an actual value of 100.0V, the indicated display could be anything from 98.8V to 101.2V. For the BK 2703B DMM used in our labs, the accuracy of the DC voltage readings for all scales is ±(0.5%+1 digit). Thus for a reading of 3.57 volts on the 20 volt scale, the accuracy is 0.5% of the reading ±0.02 V (this value was rounded to one significant digit because the meter reading is to the hundredth of a volt.

This paper describes the mechanism of a voltmeter that can measure voltage up to 30.00 V with a resolution of 10mV. In this voltmeter the achieved accuracy is quite good so that it can be used where precise voltage measurement is required. Keywords: Voltmeter, precision, staircase, ADC, DAC. I. INTRODUCTION A voltmeter is an instrument used for measuring electrical potential difference between two points of an electrical circuit. Voltage is a fundamental quantity that is important in every phase of electrical engineering from power systems to voltages inside VLSI chip [1]. Various physical quantity that can be converted to voltage using sensors, e.g. pressure, temperature, etc. can be displayed on a voltmeter. Therefore measurement of voltage is an area of concern in a wide range of discipline. Operating range may vary depending on the area under consideration. In power line voltage is in kV range, whereas voltage produced by nerve cells is in mV range.
